They have specific jobs to do in a chord progression, connecting
the seven basic chords, so their use is very logical and predictable.
Let’s look at the 1/3 chord. It’s always next to a 4 chord.
Using the key of G as an example, the 1/3 chord would be a G/B.
The top letter (or number) indicates the chord (G), and the
bottom one stands for the bass note (or lowest note) of the
chord (B, second fret, fifth string). If you look at the chord
diagram, you’ll see that it’s just a G chord with a different
bass note. The B note is already in the chord, so all you’re
doing is leaving out the usual G bass note.
If you’re strumming a guitar in an undisciplined manner, hitting
all the strings every time you strum, you won’t be able to hear
the difference between a G chord and a G/B. Play a G chord this
way: hit the bass-note G (third fret, sixth string) by itself
first, then strum the rest of the strings. Now, to play the
G/B, hit the bass-note B (second fret, fifth string) and then
strum. Now, do the same thing with a C chord: hit the C note
(third fret, fifth string) first and then strum. Hitting the
correct bass note is the key. In the G to G/B to C chord progression,
you can hear the bass note walk up from G to B to C.
Here’s how that progression might lead back to the 1 chord:
G G/B C D7 G
1 1/3 4 57 1
So any time you want to go from a 1 chord to a 4 chord, you
can connect them with a 1/3. That’s the first of the 1/3 chord’s
two jobs. The second job is connecting a 4 to a 2m. In the key
of G, the progression would be C–G/B–Am, as in this example:
C G/B Am D7 G
4 1/3 2m 57 1
Now for the 5/7 chord. This one’s really easy. The 5/7 chord
always connects a 1 chord to a 6m chord, no matter which comes
first. So, in the key of G, it would be G–D/F#–Em (1 to 5/7
to 6m) or Em–D/F#–G (6m to 5/7 to 1).

ADDING COLOR
OK, now we’ve got our basic major and minor chords and we know
how to connect them with our two connectors, but suppose we
want to add more color or texture to our songs.
The most important color chords are the add9 and sus4 chords.
Let’s start with the add9 chords. Using the key of G as an example,
let’s play a Gadd9:

If you want to add an edgy blues or rock
sound to your songs, try these two chords: the b3 and the b7.
In the key of G, they would be Bb and F. Try them along with the
1, 4, and 5 chords (and go easy on the minors, connectors, and
color chords). |
